I'm not sure if this is even possible but lets say we have an array of strings and need to match them up with a corresponding array of images. Like :
["Patriots", "Broncos", "Cowboys"] = [pat.png, bronc.png, cow.png]
I've tried with the map function but it doesn't seem to work:
let footballArray = ["Patriots", "Broncos", "Cowboys"].map({return [pat.png, bronc.png, cow.png] })
Any help solving this issue is appreciated!
You can create dictionary like this from both sequence.
let a = ["Patriots", "Broncos", "Cowboys"]
let b = ["pat.png", "bronc.png", "cow.png"]
var footballDict: [String : String] = [:]
zip(a, b).forEach { footballDict[$0] = $1 }
You can try
let footballArray = [String : String] = ["Patriots" : "pat.png", "Broncos" : "bronc.png", "Cowboys" : "cow.png"]
Or view here
this is how you can add the extension to your strings using .map
let footballArray = ["Patriots", "Broncos", "Cowboys"].map({ (value: String) -> String in
return value + ".png"
If you're talking about how to combine two arrays into one, you can use zip:
struct Team {
let teamName: String
let imageName: String
}
let teamNames = ["Patriots", "Broncos", "Cowboys"]
let imageNames = ["pat.png", "bronc.png", "cow.png"]
let teams = zip(teamNames, imageNames).map { (teamName, imageName) in
Team(teamName: teamName, imageName: imageName)
}
That yields an array of Team objects, built using elements from those two arrays.
